Embodiments are directed to an electromagnetic memory device having a memory cell and an encapsulation layer formed over the memory cell. The memory cell may include a magnetic tunnel junction (MTJ), and the encapsulation layer may be formed from a layer of hydrogenated amorphous silicon. Amorphous silicon improves the coercivity of the MTJ but by itself is conductive. Adding hydrogen to amorphous silicon passivates dangling bonds of the amorphous silicon, thereby reducing the ability of the resulting hydrogenated amorphous silicon layer to provide a parasitic current path to the MTJ. The hydrogenated amorphous silicon layer may be formed using a plasma-enhanced chemical vapor deposition, which can be tuned to enable a hydrogen level of approximately 10 to approximately 20 percent. By keeping subsequent processing operations at or below about 400 Celsius, the resulting layer of hydrogenated amorphous silicon can maintain its hydrogen level of approximately 10 to 20 percent.

The Supreme Court has temporarily put on hold the release of redacted grand jury material from the Russia investigation to a House panel. The Trump administration is trying to block the release. Last October, a district court judge ruled the Justice Department had to turn over the materials, which were blacked out, from former special counsel Robert Mueller's report into Russian interference in the 2016 election. An appeals court upheld the decision , but the Trump administration, hoping to keep the evidence secret, appealed to the Supreme Court. Chief Justice John Roberts' order temporarily stops the process. Lawyers for the House Judiciary Committee have until May 18 to file their response to the Justice Department's attempts to keep the materials from the House panel. The Justice Department had until Monday to turn over the material following the appeals court order. But on Thursday, the Trump administration asked the Supreme Court to block Congress from seeking it, saying, "The
